A comprehensive experimental study of five fundamental phenothiazine geometries increasing the diversity of the phenothiazine dye class for dye-sensitized solar cells
Buene, Audun Formo; Hagfeldt, Anders; Hoff, Bård Helge (Journal article; Peer reviewed, 2019)Phenothiazine is a versatile scaffold frequently used in both pharmaceutical and photovoltaic applications. Still, the structural diversity within the class of phenothiazine sensitizers for dye-sensitized solar cells is ... -
Auxiliary donors for phenothiazine sensitizers for dye-sensitized solar cells – how important are they really?
Buene, Audun Formo; Ose, Eline Ekornhol; Zakariassen, Ane Garborg; Hagfeldt, Anders; Hoff, Bård Helge (Journal article; Peer reviewed, 2019)Auxiliary donors are common design motifs for phenothiazine sensitizers for dye-sensitized solar cells. Despite this, there are only a few reports on their overall contribution to the photon-to-electron conversion efficiency. ... -
Effect of Auxiliary Donors on 3,8-Phenothiazine Dyes for Dye-Sensitized Solar Cells
Buene, Audun Formo; Christensen, Mats; Hoff, Bård Helge (Journal article; Peer reviewed, 2019)Phenothiazines are one of the more common dye scaffolds for dye-sensitized solar cells. However, these sensitizers are exclusively based on a 3,7-substitution pattern. Herein, we have synthesized and characterized novel ... -
Effect of furan π-spacer and triethylene oxide methyl ether substituents on performance of phenothiazine sensitizers in dye-sensitized solar cells
Buene, Audun Formo; Boholm, Nanna; Hagfeldt, Anders; Hoff, Bård Helge (Journal article; Peer reviewed, 2019)Conjugated π-spacers are used to improve the light harvesting properties of sensitizers for dye-sensitized solar cells. In several recent works, furan has outperformed other popular π-spacers such as thiophene and phenyl. ... -
Effect of π-linkers on phenothiazine sensitizers for dye-sensitized solar cells
Buene, Audun Formo; Uggerud, Nora; Economopoulos, Solon; Gautun, Odd Reidar; Hoff, Bård Helge (Journal article; Peer reviewed, 2018)Eleven new dyes have been synthesized in order to investigate the effect of five different π-spacers and two different auxiliary donors in phenothiazine-based sensitizers for dye-sensitized solar cells. The target molecules ... -
First Report of Chenodeoxycholic Acid–Substituted Dyes Improving the Dye Monolayer Quality in Dye-Sensitized Solar Cells
Buene, Audun Formo; Almenningen, David Moe; Hagfeldt, Anders; Gautun, Odd Reidar; Hoff, Bård Helge (Journal article, 2020)Chenodeoxycholic acid (CDCA) is the most used anti-aggregation additive in dye-sensitized solar cells since its introduction to the field in 1993. However, effective suppression of dye aggregation comes at the cost of ... -
Investigating the Effect of the Auxiliary Donor in Phenothiazine-Based Dye-Sensitized Solar Cells
Ose, Eline Ekornhol (Master thesis, 2017)The growing need for green energy gives good opportunities for DSSC to complement the silicon-based solar cells of today. The advantages are many; they can be cheap, lightweight, flexible, aesthetically beautiful and ... -
Molecular Engineering and Photovoltaic Evaluation of Phenothiazine and Triarylamine Dyes for Dye-Sensitized Solar Cells
Buene, Audun Formo (Doctoral theses at NTNU;2019:254, Doctoral thesis, 2019)De klimatiske konsekvensene av økende CO2 utslipp har vært godt kjent siden Svante Arrhenius’ tidlige forskning i 1896. Han korrelerte global temperatur og atmosfærisk CO2-konsentrasjon, og gav nøyaktige estimater på den ... -
Synthesis and Characterisation of 3,8-Substituted 10H-Phenothiazine Dyes for Use in Dye-Sensitised Solar Cells
Christensen, Mats (Master thesis, 2019)Ettersom verdens energibehov fortsetter å vokse, og de forferdelige konsekvensene av global oppvarming kan føles over hele verden, trengs det nye grønne og fornybare energikilder. Fargestoffbaserte solceller (Dye-sensitised ... -
Synthesis of Thieno[2,3-d]pyrimidine-Based EGFR-TK Inhibitors with Improved Solubility and Metabolic Stability
Buene, Audun Formo (Master thesis, 2015)The objective of this master s thesis was to synthesize EGFR tyrosine kinase inhibitors with enhanced aqueous solubility, metabolic stability and potency compared with commercially available inhibitors. Improving these ...
